THELUS M. BISSELL, OF SOUTH BEND, INDIAN:

PLOW.

SPECIFICATION forming part of Letters Patent No. 312,797, dated February 2%., 1885. Application filed June 30, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, THELUS M. BIssEL of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Plows; and I do hereby declare that the ibllowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure 1 is a side view of my improved plow attachment secured to a part ot'a beam. Fig. 2 is a perspective view of the bracket detached from the beam. Fig. 3 is a perspective view of the standard with plow attached. Fig. 4 is a horizontal section through the standard, showing the hook. horizontal section through the bracket, show ing the recess for said hook. Fig. 6 is a 1 erspective view of one of the gibs or clampingblocks.

This invention relates to new and improved means for fastening a jointer-standard to the bracket and the bracket to the plow-beam, as will be fully understood from the following description, when taken in connection with the annexed drawings.

A designates a plow-beam,to which is rigidly secured an angular flanged bracket, B. This bracket is constructed with a top flat part, a, having beveled flanges 12 1) formed at the front and rear. From the said part a depends perpcndicularly a flat portion, a, formed with a front straight edge, (Z, and having a hooked or beveled recess, a, and also two holes, ff.

0 designates the jointer-stan(lard, having thejointer D rigidly secured to its lower end in anysuitable manner. The standard 6 is constructed with a rib, g, on its front edge,

adapted to fit against the straight edge d of the bracket B. It is also constructed with a hook, h, near its upper end on one side,wl1ich hook is adapted to engage in the recess a in bracket B. Two holes, f f, are made through the standard C for the reception of a bolt, e, which is passed through either one of the holcsff, for assisting in securing the stand- The hook h is much narrower vertically than the length of the recess Fig. 5 is a' e, for the purpose of allowing vertical adjustment of the standard on the bracket when the bolt 2' is removed. The holes fff f are spaced so as to be different distances apart for the following reason: Suppose the standard to be set to its place, with the hook h in the recess a and the rib 9 against the straight edge (1 of the bracket. It can be slid upward until the lower hole, f, coincides with the holef. Then by passing a bolt through said holes and screwing up the nut on the same the standard is firmly bound to the bracket. Now, it is evident that by taking out the bolt and lowering the standard the holes will coincide as follows: first, f with f,- second, f withf; third, f withf, and, fourth,f with f, thus affording ionr adjustments of the jointer vertically, and in each case the standard is firmly bound to the bracket with a single bolt. The bracket is rigidly secured to the plow-beam by means of gibs or blocks G, having beveled lips it, that engage with the beveled flanges b b on the ends ot'the bracket. The gibs G are perforated and receive bolts 1 Z, that are passed vertically through the beam and have nuts screwed on them, which rigidly bind the upper surface of the bracket to the lower side of the plow-bean1. 'As the gibs are allowed to turn about their bolts when the nuts thereon are loosened, the bracket can be adjusted to the right or left suiiicicntly to a]- low the jointer to be set in line with the plow.

Having described my invention, what I claim is The combination, with the standard B, having straight edge, a beveled recess, and apertures ff at one side, of thejointer-standard C, flanged at one edge, as indicated by the letter 9, and provided with a hook, it, adapted to hook into the beveled recess 6 and hold the flange to the straight edge, the said jointer- \Vitncsses:
